PIPE-COUPLE? Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed May 23, 1907. Serial No. 375,286.

pm, a citizen of the United States of Amer- To all whom Lt may concern. I I I I ma, residing at Huntington, in the countyofCabell and State of \Vest Virginia, have invented new and useful Improvements in Pipe-Couplings, of which the following is a specification. l This invention relates to pipe couplings, I and one of the principal objects of the same is to provide a coupling which can be quickly and easily renewed when any of the parts become worn or injured without disturbing the pipe sections.

Another object of the invention is to provide a pipe coupling in which one of the parts is made in section so that it can be readily removed for repairs or renewals.

These and other objects may be attained by means of the construction illustrated in I the accompanying drawing, in which Figure 1 a front elevation of a pipe section, and showing one of my pipe couplings in section and the others in elevation. Fig. 2 is a detail perspective view showing one section of the inner member of my pipe coupling. Fig. 3 is a perspective view of the outer member of my pipe section.

Referring to the drawing for a more pan ticular description of my invention, the numeral 1 designates a connecting pipe section provided upon its ends with a sleeve 2 provided with a flange 3 beveled upon, its outer surface, as at 4, to fit the inwardly beveled portion of the pipe section. The pipe section is: providcdnvith a reduced portion. 6, havin screw. threads 7 formed thereon, and fitted the threads 7 is a sectional member preferably composed of two sections, each provided with interior screw threads 8, an outwardly extending flange 9, and an inwardly extending flange 10 at the outer end thereof, said sections each having exterior screw threads .11, and spanner grooves 12. The flange 10 engages the outer surface of theflange 4- of the sleeve 52-, while the threads 8 engage the threads 7 on the reduced portion Fitted over the sec tional members is a collar 13 having internal. threads 11 of the two sections of the coupling, said collar having an outwardly extending flange 15 provided with spanner grooves 16.

With a pipe coupling made in accordance with my invention, whenever it becomes necessary to renew any of the parts, the collar 13 is removed by a spanner engaging the grooves 16. When the collar 13 is removed from the sectional members, the latter may be withdrawn from the reduced portion 6 for repairs or renewals when the collar may be screwed tightly in place, without the llir cessity of disturbing the pipe connection 1.

From the foregoing itwill be obvious that a pipe coupling made in accordance with my invention is of simple construction, can be quickly attached to and detached from the pipe sections, and will permit of repairs and renewals without disturbing the pipe connection.

Having thus described the invention, what 1 claim is:

The. herein described pipe coupling comprising a coupling section provided at each. of its ends with an inte ral sleeve formin an enlarged portion eac having a beveled flange at its outer end, pipe sections, each provided with a reduced and beveled outer end to fit the beveled end of the sleeve, said reduced ends each having an exterior threaded portion, sectional coupling members each provided with interior screw threads to engage the exterior threaded portion of the pipe section and each having an outwardly extending flange at one end and an inwardly extending fiang at the opposite end thereof, said last mentioned flange engaging the beveled flange of the coupling section, said coupling members having exterior screw threads ad acent to theoutwardlv extending flange, an a collar provided with interior screw threads at one end tofit the exterior threads of said couplin members, said collar having an outward y projecting flange provided with spanner grooves.

In testimony whereof, I aflix my signature in presence of two witnesses.
